Rome, February 26 - Beppe Grillo, whose Five Star Movement made significant gains at Italian elections on a protest platform, accused rival candidate Silvio Berlusconi of buying votes by promising Italians to rebate an unpopular property tax called IMU. "Berlusconi bought the votes with (promises to reverse) IMU. It's a dramatic move," he said. The Five Star Movement claimed 25.55% of the votes for the House, more than any other individual party, and took a total of 162 seats across both chambers of parliament. Berlusconi's centre-right coalition came second in the contests for both the Senate and the Lower House. Although Berlusconi did not have enough seats to form a government, his supporters have heralded the results, as his bloc was trailing by double digits in the polls at the start of the campaign.
